Welcome to our forum C7STGRA! Sorry to read of your bumper scrapes. You did not indicate how you think you got them which would be helpful in our suggesting ways to avoid them. Depending on the type and depth, you might be able to try a scratch removing polish (carefully). A picture or two might also aid some of our members in providing suggestions.
